d. None of the above

Answer:

A torque wrench should be used to tighten each wheel lug nut.

When installing wheels on a vehicle, it is crucial for a technician to use a torque wrench to tighten each wheel lug nut. A torque wrench is a specialized tool that allows the technician to apply the correct amount of torque, or twisting force, to the lug nuts.

This precision in tightening the lug nuts is essential because over-tightening or under-tightening can lead to various issues such as wheel imbalance or even wheel detachment while driving. By using a torque wrench, the technician ensures that the lug nuts are tightened to the manufacturer's specified torque requirements, promoting safety and optimal performance.

Overall, the use of a torque wrench in wheel installation is a simple yet effective practice that can prevent potential accidents and damage, making it a vital step in the servicing process.
